Spiralwound Gaskets are one of the most commonly used metal gaskets. They are extremely versatile and offer an excellent seal in a wide variety of applications. The Spiralwound is manufactured by wrapping alternating layers of thin metal and a soft gasket filler material such as flexible graphite or PTFE. The chevron-shaped profile of the gasket provides resilience and a “spring like” characteristic that enhances the performance of the gasket.

The company manufactures strictly to the standards as set forth by ASME B16.20 (formerly API 601), DIN 2699 and British Standards.

LG-13 The LG-13 is the most common profile of Spiralwound gasket and used extensively in ANSI B16.5 flanges. The gaskets consist of a metal guide ring (or sometimes referred to as a centering ring) and a Spiralwound sealing element. This profile is normally used in raised and flat faced flanged. The outer ring is often made of carbon steel (painted or zinc plated to prevent corrosion) but can be made of alloys for higher temperature and more severe medium applications.
